"Rihanna rocks a bright pink coat as she heads into the recording studio on Wednesday night (October 24) in West Hollywood, Calif.
“It’s crunch time #pressure,” the 24-year-old singer tweeted that evening about her album Unapologetic, due out in stores on November 19.
Ri also showed off her new half shaved head, which she sported on the set of her music video “Diamonds” over the weekend."
